EYEGLASSES.

SPECIFICATION forming part of Letters Patent NO. 766,569, dated August2, 1904.

Application filed April 11, 1903.

To all 1072,0111, it puny concern.-

Be it known that I, LEO F. ADT, of Troy. in the county of Rensselaer andState of New York, have invented certain new and useful Improvements inEyeglasses; and l, dohereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to thereferonce-numerals marked thereon.

My present invention relates to eyeglasses, and particularly to thatclass in which the lenses are secured to a relatively inelastic bridgeand in which the guards or holdingpads are yieldingly secured to thelenses or frame and are provided with operating portions by which saidpads maybe manipulated and the glasses readily applied to and removedfrom the nose of the wearer.

The invention consists in certain improvements and combinations wherebythe parts may be readily constructed and assembled and the glassessecured and removed in the best manner, all as will be more fullydescribed, and the novel features pointed out in the claims at the endof the specification.

In the drawings. Figure 1 is a front elevation of a pair of glassesembodying my improvements. Fig. 2 is a horizontal sectional view of thesame, taken through the attacl ing-clips and the guard-supports. Fig. 3is a front elevation of another form of the invention. the same similarto Fig. 2.

Similar reference-numerals in the several figures indicate similarparts.

The lenses (indicated by 1) are provided at their inner edges with theusual perforations, through which pass the securing-screws 2, serving toconnect the parts with the bridge 3. 1n the present instance the clips4: on the inner edges of the lenses are provided with perforated lugsextending on opposite sides of the lenses and in addition with lugs 5,extending rearwardly at the inner edge of the clips and provided withapertures for the passage of the ends of the bridge 3. The ends of theFig. 4. is a horizontal sectional view of bridge and the clips and lugsare perforated for the passage of securing-screws 2, having I X one ofthe parts.

other end to engage corresponding threads in Thus in Figs. 1 and 2 theheads of the screws are arranged at the front of the glasses, and theopposite ends engage threaded apertures in the bridge 3, while in Fig.at the screws pass through in the opposite direction. the threaded endengaging the outer lugs of the clips.

7 7 indicate the pads, guards, or portions adapted to bear upon the noseof the wearer and formed upon or connected to the ends of the supports.These supports or arms are each composed of a single strip of flatspring metal, one end of which is attached to the lenses and bridge andextend rearwardly, being formed into loops 11, thence forwardly of thelenses, passing through apertures 8 in the bridge, thence outwardly infront of the lenses, where they are bentsharply, formingloops l0, andreturned to the rear of the lenses through the apertures in the bridge,their extreme ends having the pads or guards attached thereto in anysuitable manner. It is immaterial in exactly what manner the ends of thesprings are attached to the clips, and in Fig. 2 l have shown the end ofthe guard-srmport located between the bridge end and the clip andextending rearwardly of the clip; but I prefer the construction shown inFig. 4, in which the spring is bent sharply, then passed inwardlythrough the aperture in the lug 5 of the clip, and thence rearwardly toform the loop 11, and through the bridge-aperture, the head of thesecuring-screw in this instance engaging said spring.

From the above construction it will be seen that the guards 7 aremounted upon the extreme ends of the relatively long springs providedwith two loops 10 and 11, serving to yieldingly engage the wearers nose,but with sufiicient pressure to hold the glasses firmly in position, andthe outer forwardly-projecting loops lO'serve as handles by means ofwhich the operator may separate the guards or pads, as shown in dottedlines in Fig. 2, and thereby readily apply or remove the glasses fromthe nose. \Vhen the glasses are held upon the nose of the wearer, theprincipal spring-pressure is exerted between the pads at one end theheads 6 and threaded at the l orguardsandtl1eloopsl0.and when theguardsare separated by pressing together the outer ends of the loops the armsare then turned also on a center approximating that of the loops'll, sothat an extreme separation of the guards will be obtained without undulystraining the parts. In order to obtain an increased movement of theguards when separated with a slighter movement of the ends of the loops10 than would otherwise be the case, I form the apertures 8 in thebridge of such a length that when the arms or supports are moved aboutthe loops 11, as centers their outer or free ends will engage and befulcrumed on the I structed of flat spring material, and by rea- 'cationis intended to mean the part formed son of the forward and rearwardloops the pads or guards are capable of a wide variation of adjustmentwithout changing the length of the bridge, so that glasses provided withmy invention may be readily adapted to persons having different facialcharacteristics by the Optician. I I

The term "loops employed in the specifiby bending the material back uponitself, and though I prefer that the portions called loops 11 shall beof a rounded contour, as they afford an easy movement of the parts, 1 donot desire to be confined to this construction.

I claim as my inventionl. The combination with the lenses and the bridgeconnecting them, of a pair of spring guard-arms secured at their ends tothe bridge and lenses in rear of the latter thence extending rearwardlyand forwardly again and passing between the lenses,thence forwardly andoutwardly thence rearwardly between the lenses and provided at theirfree ends with opposing guards or nose-engaging portions.

2. The combination with the lenses and the bridge connecting them, of apair of spring guard-arms each connected at one end to the lenses andbridge and formed into returnbends in rear and in front respectively ofthe plane of the lenses and having nose-bearing portions at their freeends in rear of the lenses, the bends at the front serving as operatingportions to separate the nose-bearing portions when pressed together.

8. The combination with the lenses, of the bridge having the aperturestherein and the nose-guard arms secured at the ends, said arms extendingforwardly and rearwardly through the apertures in the bridge andprovided at their free ends in rear of the lenses with the nose-bearingportions.

4'. The combination with the lenses the clips having the lugs withapertures and the bridge passing through said apertures, ofthe springguard-arms clamped to the clips and bridge at their ends, thenceextending forward of the lenses and thence in rear thereof and providedwith the nose-bearing portions thereon.

5. The combination with the lenses and the bridge connecting them,.ofthe arms each constructed of a single piece of flat spring materialextending rearwardly from the lenses, thence forwardly between them andbeyond their outer faces thence rearwardly of the lenses and provided ontheir free ends with opposing nose pads or guards.

6. The combination with the lenses, of a bridge connecting them havingfulcrums, and arms fixed to the mounting and extending at the forwardand rear side of the planes of the lenses and movable relatively theretoand engaging the fulcrums whereby the ends of the arms at one side ofthe lenses may be moved toward each other to separate their oppositeends.

7. The combination with the lenses, a bridge connecting them havingfulcrums and arms extending at the forward and rear sides of the planesof the lenses and engaging the fulcrums, of means located atone side ofthe fulcrums for movably supporting the arms, I

and guards on the arms.

8. The combination with the lenses, a bridge connecting them havingfulcrums, of arms engaging the latter having their rear ends exto theopposite side of said plane beyond the fulcrums and the free ends onsaid arms engaging the fulcrums and provided with guards.
